A red die and a blue die are rolled. You win or lose money depending on the sum of the values of the two dice. If the sum is 3 or 5, you win $6. If the sum is 8 or 9, you win $1. If the sum is any other value (2, 4, 6, 7, 10, 11, or 12), you lose $2. Let X be a random variable that corresponds to your net winnings in dollars. What is the expected value of X? E[X] = Ex: 1.23
